Hi Dale, A 504 error is a Gateway Timeout. That tends to mean there may be a connection issue to the site itself...or between the frontend & backend.
I'd recommend taking a look at our Troubleshooting Guide: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove) Specifically, if the UI or REST API is misconfigured, it's possible that the UI is somehow failing to send data to the REST API. These types of errors will *never* appear in backend logs...they are only visible in your web browser (in DevTools on the Network tab). So, the best approach would be to open your browser's DevTools and try to reproduce the error. You should hopefully see a more detailed error in the Network tab (see Troubleshooting guide), which may provide you a hint as to what is going on. If it is a connection error or configuration error, then you are likely to see one of the errors listed in our Common Installation Issues here: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues In which case that page should walk you through steps to try to solve the problem. Good luck & hopefully this helps!
